Description
This function determines the arithmetic mean of all x and y coordinates in the given TPointArray TPA, and returns this as a TPoint (rounded down). An extended function with additional functionality is available as TPAMiddleEx.
Example
var
TPA: TPointArray;
MiddlePoint: TPoint;
begin
TPA := [Point(0, 0), Point(2, 2), Point(5, 10)];
MiddlePoint := TPAMiddle(TPA);
WriteLn('Middle-Point(' + IntToStr(MiddlePoint.x) + ',' + IntToStr(MiddlePoint.y) + ')');
end.Output:
Middle-Point(2,4)
